Why the margin is low
Your markup1.24×
Industry standard1.40 – 1.55×
Gap if bumped to 1.40×+$930 margin
Gap if bumped to 1.50×+$1,520 margin
Tires are your only category dragging GP%. Customers expect online price-matching on tires, but a 1.40× markup is still defensible. Quick win: ~$1,500 extra margin/yr without changing volume.
